You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball
You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 350 from the edge of the building with an initial velocity of 13 m/s and lands 57 meters away from the wall. How tall, in meters, is the building that the child is standing on?

As shown in the figure, a ball is thrown from the top of one building toward a tall building 50 m away. The initial velocity of the ball is 20 m/s at 40 degree above the horizon. How far above or below its original level will the ball strike the opposite wall. What is the velocity of the ball at the impact point (landing point)?

From the top of a 79 meter high building, a 0.53 kilogram ball is thrown directly downward with an initial speed of 10 meters per second. If the ball reaches the ground with a speed of 35 meters per second, the increase of thermal energy of the air is
PROBLEM: A ball is thrown downward from the top of a building at an angle of...
PROBLEM: A ball is thrown downward from the top of a building at an angle of 30.0° below the horizontal. The point of release is 49.0 m above the ground and the ball lands 67.7 m from the base of the building. (a) How long does it take for the ball to hit the ground? (b) Find the ball's initial speed. (c) the speed and angle of the velocity vector with respect to the horizontal at impact. Neglect air resistance.
A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building.
A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the top of the building, with positive y upwards and positive x in the direction of the throw. Part (a) How long is the ball in the air in seconds? Part (b) what must have been the initial horizontal component of the velocity, in meters per second? Part(c)...
